Do adidas running shoes run true to size?
How adidas running shoes fit: length, width and which models to size up in.
The verdict
True to size, with a few snug exceptions.
Yes: most adidas running shoes are true to size, but on the narrow side.
Length is true to size, and adidas recommends your usual size. The Adizero racers are narrow through the forefoot, so runners with wide feet often go half a size up. Wide versions are rare across the running range.

True to size, snug fit
adidas says true to size; the forefoot is narrow, so go half a size up if your feet are wide.

Between sizes?
Running shoes should leave about a thumb's width between your longest toe and the end of the shoe. Your feet swell on longer runs, so a shoe that feels just right in the shop can feel tight at mile ten. If you're between sizes, go up half a size for long runs and marathons; for short, fast race shoes, a closer fit is fine.
If your feet are wide, a wide version beats going up a size: a longer shoe adds length where you don't need it, and your foot can slide around.
Frequently asked questions
Should I size up in adidas running shoes?
Not usually. Most adidas running shoes fit in your normal size. The exceptions are the Adizero Adios Pro 5 and the Adizero Evo SL, which fit closer: go half a size up if your feet are wide or you're between sizes.
Do adidas make wide-fit running shoes?
Not in the models we track. If you need extra room, look at brands with roomy toe boxes, such as Altra or Topo Athletic, or the wide versions from Brooks, ASICS and New Balance.
Is adidas sizing the same as Nike's?
For length, mostly yes. Both are on the narrow side, so if your feet are wide, half a size up helps in either.
